Thanks for testing! .. hmm weird,
- you have started navigation before GPS was turned on or after?
- you started navigation from detail of track (then Locus Map search for nearest trackpoint based on your current position) or you tapped on "Navigate" in small popup menu directly on map (in this case, currently selected trackpoint is "target")
Change in latest version is, that if "GPS source" is enabled in Locus, then "network locations" (indicated by orange GPS icon) are simply ignored. So if Locus Map started navigation on incorrect trackpoint, it may be because navigation was started before GPS in Locus was started (then current map center was used) or you tapped somewhere to end of track and started navigation from map popup. .. or something is still wrong, hmm.
